HIP-TO-WAIST AND WAIST-TO-CROTCH SILHOUETTE(S) OF ABSORBENT ARTICLE(S) COMPRISING BEAMED ELASTICS
The present disclosure relates to absorbent articles comprising belts comprising one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Hip-to-Waist Silhouette from about 0.8 to about 1.1 and a Product Waist-to-Crotch Silhouette from about 0.8 to about 2.0 to provide for the advantages described above.
Methods and apparatuses for making elastomeric laminates
The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. Aspects of the methods for assembling elastomeric laminates may utilize elastic strands supplied from beams that may be joined with first and second substrates, and may be configured to carry out various types of operations, such as bonding and splicing operations.
Absorbent articles having texture zones forming background patterns and macro patterns
An absorbent article comprises first and second substrates and one or more elastic elements disposed at least partially intermediate the substrates. The second substrate is attached to the first substrate and/or to portions of the elastic elements. The absorbent article comprises an adhesive having a first and second pattern of elements disposed on first substrate, and first and second texture zones. The first texture zone comprises a first portion of the substrates, a first portion of the elastic elements, and the first pattern of elements of the adhesive and forms a background pattern in the first portion of the substrates. The second texture zone comprises a second portion of the substrates, a second portion of the one or more elastic elements, and the second pattern of elements of the adhesive and forms a macro pattern in the second portion of the substrates.
METHOD AND APPARATUS FOR MANUFACTURING ABSORBENT SANITARY PRODUCTS AND AN ABSORBENT SANITARY PRODUCT
A method for manufacturing absorbent sanitary products, comprising the steps of: forming a first and a second continuous elastic band, which are movable parallel to each other in a machine direction, fixing a plurality of absorbent panels between said first and second continuous elastic bands, arranged in a direction transverse to the machine direction, and spaced apart in said machine direction, wherein each of said elastic bands is formed by means of a method comprising the steps of: continuously feeding a plurality of tensioned elastic threads (30) in said machine direction, continuously feeding a pair of non-elastic webs arranged on opposite sides of said plurality of elastic threads, welding said pair of non-elastic webs to each other by means of a welding pattern comprising anchoring welds and/or containing and guiding welds.
LAMINATE(S) COMPRISING BEAMED ELASTICS AND ABSORBENT ARTICLE(S) COMPRISING SAID LAMINATE(S)
The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.
DISPOSABLE ABSORBENT ARTICLES HAVING CUFFS OF IMPROVED STRETCH LAMINATE STRUCTURE
An absorbent article having longitudinal cuffs of improved structure is disclosed. The improved cuffs may be elasticized by a plurality of elastic strands that are substantially greater in number, closer in spacing, lower in pre-strain, and lower in decitex, or any combination of these, as compared with those in conventional articles. This combination of features results in ruffles or gathers of cuff material joined to the elastic strands that are substantially greater in machine-direction frequency and substantially lesser in z-direction amplitude, than those in conventional articles. As a result, the cuff structure lies more closely and evenly against the wearer's skin, has an improved, more cloth-like appearance, provides improved gasketing, and provides improved wearer comfort, as compared with cuff structures in conventional articles. A method for manufacturing articles with such cuff structures, utilizing a warp beam as a supply mechanism, is also disclosed.
LENGTH-TO-WAIST SILHOUETTE(S) OF ABSORBENT ARTICLE(S) COMPRISING BEAMED ELASTICS
The present disclosure relates to absorbent articles comprising belts comprising one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or low decitex (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand Test in the Method below) under the elastics, while providing adequate Section-Modulus of (between about 2 gf/mm and 15 gf/mm), resulting in a Product Length-to-Waist Silhouette that is within from about −0.3 to about 0.3 of the Target Body Length-to-Waist Silhouette to make the article conform better to the body of the wearer at a lower Pressure-Under-Strand, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.
Method and apparatus for assembling absorbent articles
The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.
Underpants-style disposable diaper and manufacturing method therefor
A method of producing an underpants-type disposable diaper includes forming an outer member having a non-stretchable region disposed in an intermediate region in the width direction and stretchable regions disposed on the two sides of the non-stretchable region in the width direction by: fixing elastic members to an inner sheet layer and an outer sheet layer in at least two edge portions of portions to be the stretchable regions without fixing the elastic members to the inner sheet layer nor the outer sheet layer in a portion to be the non-stretchable region; disposing a graphic sheet and disposing a no-extra-sheet region between the inner sheet layer and the outer sheet layer in the side portion of the non-stretchable region; cutting the elastic members and leaving cut marks and idle elastic members over the no-extra-sheet region; and leaving the elastic members in a region overlapping with the graphic sheet uncut.
